Answer 7

Polymixins and polyenes

Question 8

When the antibiotic binds to the cell membrane it makes it more ____ to get into the cell.

Answer 8

Permeable

Question 9

Polyenes are used specifically against

Answer 9

Fungis

Question 10

Penicillin, bacitracin, and cephalon sporins target what

Answer 10

The cell wall (cell wall synthesis)

Question 11

Why won’t penicillin effect human cells?

Answer 11

Because we do not have cell walls with peptidoglycan layers.

Question 12

What layer does penicillin target

Answer 12

Peptidoglycan

Question 13

Quinolenes and nalioixic acids inhibit

Answer 13

Inhibition of DNA synthesis

Question 14

Rifamycin inhibits

Answer 14

Inhibition of RNA synthesis

Question 15

50s is targeted by

Answer 15

erythromycin and chloramphenicol

Question 16

30s is targeted by

Answer 16

Tetracycline
Stetomycin
Gentamycin

Question 17

5 methods in which antibiotics target a cell

Answer 17

1) cell membrane
2) cell wall synthesis
3) inhibition of RNA and DNA synthesis
4) inhibition of protein synthesis
5) inhibition of folic acid metabolism

Question 18

Why are the antibiotics that target protein synthesis Bacteriostatic?

Answer 18

Because the ribosomes will not be able to make any proteins but the cell is still alive.

Question 19

PABA converts to

Answer 19

Folate

Question 20

Drugs that inhibit folic acid metabolism

Answer 20

Sulfonamides
Trimetoprim

Question 21

Do humans synthesize folic acid?

Answer 21

No, thats why sulfonamides and trimetoprim are effective.
